ABSTRACT
The family Loranthaceae Juss. is characterized mainly by its hemiparasitic habit. It has high representativeness in the world, occurring, in Brazil, from the humid forests like the Atlantic Rain Forest, to the xeric areas like the Caatinga vegetation. This work presents the taxonomic study of Loranthaceae at the Parque Nacional do Catimbau, semiarid region on Pernambuco state, northeast of Brazil. In the studied area, four species belonging to the genera Psittacanthus and Struthanthus were recorded. Struthanthus confertus Mart. is recorded for the first time to the state of Pernambuco. A key for the separation of species based on morphological descriptions was elaborated. Data on the period of flowering and fruiting and habitat also were provided to the species.
